摘要

Disclosed is an erecting same-size lens array plate (11) provided with a first lens array plate (24) in which a plurality of convex lenses (25) are provided on both surfaces, a second lens array plate (26) in which a plurality of convex lenses (25) are provided on both surfaces and which is disposed so as to face the first lens array plate (24), and a light-blocking member (27) disposed between the first lens array plate (24) and the second lens array plate (26) and adapted to block light not contributing to the image formation. The light-blocking member (27) is longer in the horizontal scan direction than the first lens array plate (24) and the second lens array plate (26).
